[FE-discuss] List of all errors encountered in a form

[J***@js3d.Co.Uk]

Hi,

Is there an easy way to access any errors which may have been flagged in a
schema in a final chained validator? I want to insert a generic message at
the top of the page letting the user know that the form has errors.
I was approaching this through a custom chained_validator but I'm unsure of
what value to test against to see if any errors have allready occoured,
error_dict dosen't seem to exist. This is in pylons using @validate
decorator.

An alternative [hacky ]fix to my problem and also something I'm having no
luck with would be to be able to anchor to the top of the form when the
page is reloaded, but I've no idea how to achieve it.

Any help much appreciated.

Jules

Chained validators don't have access to previous errors. The actual
validation produces an exception that contains all the errors. @validate
then runs those through htmlfill. I'm not sure if there's a way to get into
@validate; you might want to ask on the Pylons list.

I'm not sure what you mean? Oh, like redirect to #top? You could change to
<form action="page#top">; for successful submissions that shouldn't do
anything, but for unsuccessful submissions you'd go to the top.

I just checked the pylons @validate (
http://pylonshq.com/project/pylonshq/browser/pylons/decorators/__init__.py),
and it places the entire errors dictionary into c.form_errors.
